Kabel Deutschland has launched a dedicated trial in Berlin, Hamburg and Munich of the next generation DVB-C2 standard. The operator is testing the technology on Channel 4 (794MHz) running TV channels in DVB-C2.
“The main advantages of DVB-C2 are the higher transmission efficiency and optimum adaptability to the characteristics of different cable networks,” said Lorenz Glatz, CTO, Kabel Deutschland. “This is achieved by the new OFDM modulation method and the efficient LDPC error protection, both are being brought in through the new DOCSIS 3.1 standard. The introduction of the new standards will enhance the already very powerful broadband infrastructure further and still provide more extensive services. Cable customers should be thrilled.”
DVB-C2 1024-QAM modulation is used at a 3/4 FEC (forward error correction), which is run over DVB-C is spectral efficiency 46% higher without changing the transmission signal level. “We hope that the manufacturing industry will soon bring devices with combined DVB-C2/DVB-C-reception capability in the market so that we can then expand our DVB-C2 and offer step by step allows you to migrate to DVB-C2 will, ” said Frank Hellemink, vice president, engineering, Kabel Deutschland.
ARRIS, Astro, Strobel Communication Systems and Sony all provided DVB-C2 equipment for the trial.
